It is composed of a sloping portion 46 formed so as to be wide, and has a hook-shaped cross section as a whole.

The top surface of the upper wall 45 of the pressing portion 47 contacts the lower surface of the base wall 4 of the cap body A, and the side peripheral surface of the inclined portion 46 contacts the inner peripheral surface of the lid engaging portion 8 of the mounting cylinder portion 3. There is.
On the other hand, the lower end portion of the inclined portion 46 may contact the inner circumferential engagement convex portion 11, but it is preferable that a slight gap be formed between the lower end portion and the inner circumferential engagement convex portion 11. The pressing portion 47 can be easily attached to the cap body A.
A fitting concave line 40 that fits with the fitting convex line 13 of the fitting cylinder 6 is formed on the lower outer periphery of the partition wall part 30.
In the present embodiment, the pressing portion 47 is formed in a ring shape over the entire circumference, but the pressing portion 47 may be formed by intermittently cutting out.

Next, the mode of use and operational effects of this embodiment will be described.
In the hinge cap of the present embodiment, first, the inner plug member D having the seal S attached to the upper surface of the partition wall portion 30 is attached to the cap body A with the positioning protrusion 35 aligned with the hinge C side.

At that time, as shown in FIG. 1 (a), in the inner plug member D, the fitting recessed ridge 40 provided around the outer peripheral lower portion of the partition wall portion 30 was provided around the inner peripheral lower portion of the fitting tube 6. Since the pressing part 47 of the flange part 32 is formed into a hook shape having a space a at the bottom, the inclined part 46 of the pressing part 47 is formed on the cap main body A. When fitted to the inner peripheral surface of the lid engaging portion 8, it is deformed to the space a side, and the side peripheral surface of the inclined portion 46 can ride over the inner peripheral engaging convex portion 11 of the mounting outer tubular portion 9.
After that, in the inner plug member D, the flange portion 32 is prevented from falling off by the inner peripheral engagement convex portion 11.

Next, the closed hinge cap is capped and attached to the mouth portion 1 of the container E filled with the content liquid.
In the stoppering process, the mouth portion 1 of the container E is applied to the annular groove formed between the inner cylindrical portion 31 of the inner stopper member D and the mounting outer cylindrical portion 9 of the cap body A, and the lid B is pressed from above. Apply pressing force.
At that time, the fitting protrusion 12 of the mounting outer cylinder portion 9 rides on the fitting protrusion 2 of the mouth portion 1 and tries to push the mounting cylinder portion 3 outward from below. When the mounting outer cylinder portion 9 is deformed and pushed wider than the lid engaging portion 8 and the fitting protrusion 12 gets over the fitting protrusion 2, the deformed mounting outer cylinder portion 9 returns to its original state. Restore.
At the same time, the lower portion of the outer peripheral surface of the inner cylinder portion 31 of the inner plug member D rides on the upper end of the inner periphery of the mouth portion 1, and is inserted into the inner periphery of the mouth portion 1 while deforming the inner cylinder portion 31 inward.

The lid engaging portion 8 of the mounting cylinder portion 3 presses the inner peripheral surface of the inclined portion 46 of the pressing portion 47 of the flange portion 32 of the inner plug member D so as to return to the original shape, whereby the lid engaging portion 8 is pressed. Since the shape retention of the lid is maintained, it is possible to prevent the lid engaging portion 8 from being pulled inward by the deformation of the mounting outer tubular portion 9 and deformed inwardly by the impact of the stopper, and the lid B side. There is no influence on the fitting of the peripheral wall 21 with the entire engaged portion 23.
Further, since the mounting outer cylinder portion 9 is formed thinner than the lid engaging portion 8 and is easily deformed, the pressing force at the time of tapping can be reduced as compared with the conventional case.

Finally, the upper surface of the mouth portion 1 of the container E contacts the bottom surface of the base ring portion 43 of the flange portion 32, and the stopper is completed.
At the end of the capping, the restoring force of the mounting outer cylinder portion 9 of the cap body A causes the inner circumference of the mounting outer cylinder portion 9 and the fitting projection 12 to closely contact the outer circumference of the mouth 1 of the container E and the fitting projection 2. To do.
In addition, the inner cylinder portion 31 of the inner plug member D has a close contact property due to the restoring force that attempts to return to the outside and the pressure with which the fitting protrusion 13 of the fitting cylinder 6 of the cap body A contacts the fitting recess 40. It is possible to prevent the inner cylinder portion 31 from being deformed inward.

When the content liquid in the container E is used, a finger is put on the knob 25, the lid B of the hinge cap is opened, and the seal S attached to the upper surface of the partition 30 of the inner plug member D is picked. The part Sa is picked up with a finger, the seal S is peeled off from the partition part 30, and the spout 33 and the air introduction port 34 formed in the partition part 30 are opened.
Next, by tilting the container E in the dispensing direction (front side), the content liquid in the container E can be easily dispensed from the spout 33 through the dispensing cylinder 5 of the cap body A.
After use, by closing the lid body B again, the sealing ring 22 of the lid body B is inserted into the inner circumference of the pouring tube 5 of the cap body A, and the inside of the cap body A can be sealed. Even after opening, the lid B can be repeatedly opened and closed for use.

The hinge cap of the present invention can be used after all the content liquid in the container E has been used and then separated from the mouth 1 of the container E and discarded.
At that time, when the lid B of the hinge cap is opened, the lid B is grasped by a finger and pulled in the radial direction of the cap body A, the outer peripheral cylinder portion 7 of the cap body A is hinged to the hinge of the separating portion 14. Since the protruding piece 15a of the separation end portion 15 formed on the one end side 7a which is the C side is not connected to the outer peripheral surface of the mounting outer cylindrical portion 9, the outer peripheral cylindrical portion 7 is formed as shown in FIG. 5 (a). Then, it is easily deformed outward from the separation end portion 15, whereby the lateral rib 17 starts to break from the separation portion 14 side.

  As shown in FIG. 5B, when the lid B is further pulled in the circumferential direction of the cap body A after the breaking of the lateral ribs 17 is completed, the outer peripheral cylinder portion 7 is intermittently attached to the mounting outer cylinder portion 9. The weakening piece 19 that is disposed in a separate manner is separated while being broken, and then pulled up through the connecting portion 18 on the other end side 7b opposite to the hinge C of the separating portion 14 to remove the mounting tubular portion 3 from the mounting side. The tubular portion 9 is pulled and deformed, the fitting with the container E is released, and when the mounting tubular portion 3 is pulled upward, the inclined portion of the pressing portion 47 in which the inside plug member D has a hook-shaped cross section. 46 opens outward to return to the original shape, follows the movement of the mounting cylinder portion 3, and the fitting state is maintained, so that the inner plug member D is also pulled up, and the inner plug member D is removed together with the cap body A. It can be separated from the mouth 1 of the container E.

In the present embodiment, the hinge cap has the cap body A and the inner plug member D which are separate bodies, but the cap body and the inner plug member are integrally formed, and the mounting cylinder portion is the outer cylinder portion and the inner cylinder. It may be a hinge cap having a portion.
Further, in the present embodiment, the seal S is attached to the upper surface of the partition wall portion 30 of the inner plug member D, and the spout 33 and the air introduction port 34 opened in the partition wall portion 30 are closed, but the weakened portion is formed in the partition wall portion. Alternatively, the partition may be opened, and the partition may be unplugged with a pull ring or the like to open the spout in the partition wall.

  Since the hinge cap of the present invention forms the circumferential tear line that can tear the outer peripheral tube portion of the cap body in the circumferential direction at the time of separating and discarding, it is not necessary to provide the vertical tear line unlike the conventional case. It is easy to use and can be widely used as a hinge cap for food containers.
